management increase risk.

Improper Access Control: Excessive permissions or lack of role-based access can

lead to privilege escalation.

Outdated Software: Running unsupported versions without patches can expose

known vulnerabilities.

Insuﬃcient Logging and Monitoring: Without proper audit trails, detecting and

responding to incidents becomes diﬃcult.

Implementing Strong Authentication and Authorization

One of the foundational pillars of securing SAP Business Connector is controlling who can

access it and what actions they are permitted to perform.

Use Robust User Authentication Mechanisms

Avoid default credentials at all costs. Instead, implement strong passwords combined with

multi-factor authentication (MFA) where possible. SAP BC supports various authentication

modes, including Basic Authentication, Client Certiﬁcates, and LDAP integration.

Whenever feasible, leverage centralized identity management systems to enforce

consistent security policies across the enterprise.

Deﬁne Role-Based Access Control (RBAC)

Not all users require the same level of access. Carefully assign permissions based on the

principle of least privilege. Create distinct roles for administrators, developers, and end-

users interacting with SAP BC. Regularly review these roles to ensure they still align with

business needs and security requirements.

Securing Communication Channels in SAP Business Connector

Data integrity and conﬁdentiality during transmission are paramount.

Enforce Encrypted Protocols

Always use HTTPS instead of HTTP to encrypt data in transit. For FTP transfers, prefer

FTPS or SFTP over unencrypted FTP. Conﬁguring SAP BC to support Transport Layer

Security (TLS) ensures that messages cannot be intercepted or tampered with during

exchange.

Implement Certiﬁcate Management Best Practices

Use valid, trusted SSL/TLS certiﬁcates for all communication endpoints. Regularly update

and rotate certiﬁcates to prevent expiry or compromise. SAP BC allows you to manage

certiﬁcates within its keystore, so maintain a clean and well-organized certiﬁcate
